Not sure what's going on... I've double checked fuel-up data, deleted and re-entered, but the last two entries for my Jetta are not calculated correctly. On edit, I can confirm the odometer entry is correct, yet the trip calculation returned is way off (and so to the other calculations).
Am I missing something? FWIW... this seems to have started about the time I first used the Fuelly iPhone app...?
